Uda Serial Communications Setup - Honeywell UDA2182 User Manual

3.2 UDA Serial Communications Setup

Be sure you have an IP address that allows it to be accessible on the intended Ethernet network. Consult
your IT department or network administrator for allocating IP addresses to the UDAs as required.
You will need to set each UDA's IP address prior to network connection since every UDA is shipped with
the default IP address of 192.168.1.254. Placing multiple UDAs on the same network before they have
been given unique IP addresses will cause problems.
